BAC~GROU~D OF THE INVENTION
Field of the Invention This invention relates to the field of written communications, in general, and to remailable envelopes, in particular.
Description of the Prior Art It is common practice for businesses which solicit mail responses from various addressees to forward material to the addressees in envelopes which contain business material and preaddressed return envelopes. The practice of forwardlng return envelopes is also prevalent when bills, such as from credit card or gasoline companies, a~e sent to customers.
The preaddressed return envelope is used by each original addressee to mail the requested response to the original sender. Oftentimes the business mailings are high volume ones and are prepared by hiyh speed automatic te~hniques which may include envelope blank cutting, printing, folding and sealing, along with automatic insertion steps and automatic addressing operations. Once received by the original addressees, the outer envelopes are opened, either manually or automatically, to expose the contents.

To obviate the need for a separate forwarding envelope and a separate return envelope for each original addressee, it is known to provide remailable or "two-way"
envelopes which serve both the forwarding and the return functions. One such known two-way envelope utilizes a resealing flap carried by the back panel of the forwarding envelope, to reseal the envelope for return mailing. Many other designs are known in the patent literature. However, such prior art envelopes have encountered a variety of significant difficulties in manufacture and u~e. By way of example, many of the prior art envelopes cannot successfully be manufactured on modern, high speed automatic "web-type"
envelope making machines, and many do not lend themselves to having enclosures inserted by automatic insertion machines prior to original mailing. Additionally, known two-way envelopes oftentimes require tedious manipulation by the original addressee to prepare the envelope and insertion for remailing thus causing misuse or disuse of the return envelope and/or customer dissatisfaction. Furthermore, the desired rem~ilability of prior art envelopes can be destroyed by the use of automatic or manual envelope openers which may sever the resealing flap from the body of the envelope. There are also two-way envelopes known to the prior arl which are designed in such a manner that enclosures cannot be sent in one or both directions of envelope travel.
Examples of prior art envelopes are described in U.S. Patents Nos. 1,953,192; 2,931,559i 3,874,582; 3,9&2,689;
.-- ~
and 4,08g,418. U.S. Patent No. 1,953,192 discloses a two-way envelope folded from a single asy~etrical envelope blank which has been cut from aisheet of paper. Upon receipt by the original addressee, the envelope is opened by removing a ,I tear strip along the top edge of the envelope, thus reducing the size of the original envelope to a lesser size remailing envelope. For remailing, the original addressee must remove the enclosure from the envelope, reduce the enclosure in size to fit the smaller remailing envelope, properly place the adjusted enclosure in the remailing envelope, and then seal the remailing envelope by folding the resealing flap.
A major difficulty with this àesign is that the asymmetrical blank cannot be processed on conven~ional "web-type" envelope making machines. Additionally, the two-way mailer requires complicated modifications of the enclosure fox return mailins so that the enclosure fits within the smaller remailing envelope, and so that the return address borne by the er.closure is visible through the window. These procedures are complex, detracting from the usefulness and acceptability of the two-way envelope design.
U.S. Patent No. 2,9~1,559 describes a remailable bi.lling envelope with a resealing flap on which is printed the return address. The resealing flap is connected to the back panel along a common back top edge of the envelope.
For original mailing, the resealing flap is folded at the back top edge and stuffed w~thin the envelope pocket. The .
; i .
--r , ~ ~ J~
t~7~796 .
' envelope is thus mailed in its unsealed condition, provlding ;, no privacy or capability for enclosure information or mat~rials.
Additionally, upon receipt by the addressee, the resealing flap is vulnerable to being cut during opening of the original envelope. The potential uses of such an envelope are thus , . . . .
llmlted.
U.S. Patent No. 3,874,582 provides a two-way envelope comprising a front panel with a window, a bottom flap, two opposed side flaps with detachable upper portions and a detachable top flap. Upon receiving the envelope, the original addressee removes the three detachable portions from the envelope to form a smaller sized return envelope wlth a newly formed.top resealing flap. For return mailing, the origlnal addressee inserts a response into the envelope pocket, inserts an enclosure containing the return address so that the return address can be seen through the window, and then folds and seals the newly formed top resealing flap to the back panel. Again, the comple~ity of transforming the original envelope into a usable return envelope detxacts from the usefulness and acceptability of the two-~ay envelope design.
U.S. Patent No. 3,982,689 illustrates another two-way mailing envelope, including a window and an enclosure to be transmitted therein. The envelope is usable for return mailing by tearing a top flap from the front panel of t~.e envelope and thereby exposing a resealing flap which, being the upper portion of the back panel, is then folded c 1~'7'7'i~96 toward and attached to the front panel. Thus, the remailing envelope is smaller than the original envelope by the length of the top flap which is r!emoved by the original addressee for en~elope opening. Thus the envelope also reguires an enclosure with two address areas for exposure through the window. Additionally, opening the envelope without removing the tearable top flap will not properl~7 expose the resealing flap for folding and securing to the front panel for remaillng.
The foregoing complexities of operation, including modification of the enclosure bearing the return address, detract from the usefulness and acceptability of this envelope design.
- U.S. Patent No. ~,089,418 describes a returnable envelope consisting of a blank having a main panel and flaps foldable from each edge. For original mailing, the envelope is formed by inwardly folding twc opposed side flaps, by upwardly folding a bottom flap, and by downwardly folding a top panel. The top panel is then temporarily adhered to the outer surface of the bottom flap. For return mailing, the original addressee detaches the top panel from the back of the envelope without tearing the envelope, unfolds the envelope completely and then refolds the envelope into a diferent configuration for return mailing. Additionally, opening the envelope can sever the top panel from the main panel and destroy the envelope's designed remailability.
These disadvantages, again, detract from usefulness and a~ceptability.
'î'î'91~
From the foregoing considerations, it should be apparent that there is a great need for a remailable envelope which may be manufactured, stuffed and mailed by high speed automatic machines, which can be opened by automatic or manual envelope opening devices without destroying remailability, and which is simple in use for original mailing and remailing. The subject invention is directed to just such an envelope.
SUMMARY OF THE INVENTION
The subject invention provides an envelope formed from an envelope blank which is symmetrical about its center line, said envelope comprising a front panel having a top edge, a bottom edge and two side edges; a pair of opposed side flaps, each of which is integrally connected to said front panel at first fold lines along one of said front panel side edges; a back panel integrally connected to said front panel bottom edge at a second fold line and having a top edge and two side edges;
a resealing flap integrally connected to said back panel top edge at a third fold line; a top flap integrally connected to said front panel top edge at a fourth fold line; first adhesive means for securing said side flaps in overlying relation to said back panel folded along said front panel bottom edge to overlie a portion of the inner face of said front panel; second adhesive means for securing said top flap in overlying relation to the outer face of said back panel to seal the envelope for first mailing; and third adhesive means for securing said reseal-ing flap in overlying relation to the outer face of said front panel to seal the envelope for second mailing. Being symmetxical about its center line, the envelope blank readily may be cut, printed, folded, and formed into an envelope in "web-type" automatic envelope making machines.
From another aspect, the invention provides a method of making the envelope as aforesaid, the method comprising the ti steps of: folding said resealing flap along said third fold line to overlie a portion of the inner face of said back panel;
folding said back panel along said second fold line to overlie the inner face of said front panel; and folding and securing by said first adhesive means said side flaps in overlying relation to said back panel.
In preparation for original mailing, the envelope blank is folded so that the common edge between the resealing flap and the back panel is at an appropriate spacing below the top edge of the front panel when the back panel is folded to overlie the front panel. The allowance of this spacing enables any enclosures to automatically be inserted into the envelope by automatic insertion machines.
Prior to original mailing, the top flap is adhesively sealed to the back panel of the envelope providing security and privacy in mailing. In one embodiment, the envelope is received by the original addressee and is opened by removing the tear strip from the top flap or by opening the envelope along its top edge by conventional automatic or by manual opening devices.
The spacing referred to above also protects the resealing flap from inadvertently being severed from the back panel if the envelope opened with automatic or manual opening devices. In another embodiment, the envelope is opened by removing a tear strip located on the front panel or by opening the envelope along its top edge by manual or automatic opening devices as noted above. The original addressee removes any contents of the envelope, pulls the resealing flap from the envelope folds, and inserts what is to be remailed within the envelope pocket.
In one embodiment, the original addressee folds and secures the xesealing flap over the front panel or window thereby exposing for mailing the return address borne by the outer side of the resealing flap. In another embodiment, the original addressee '7~
folds and secures to the front panel a shorter resealing flap which does not cover the entire viewing window. In all embodi-ments, placing the envelope in its remailing configuration does not require complex manipulation, and does not reduce the length or the width of the envelope as originally mailed.
Advantages of this invention will further become apparent hereinafter and with reference to the accompanying drawings.

I DESCRIPTION OF THE PREFERRED EMBODIMENTS
"
The subject invention will now be described with reference to the drawings, in which Figure 1 illustrates an envelope blank made frGm paper or other suitable matexial and generally designated by the numeral 10. Envelope blank 10 includes a front panel 11, a pair of opposed foldable side flaps 12 and 13, a top flap 14, a back panel 15, and a resealing flap 16. The side flaps 12 and 13 are integrally connected to the front panel 11 along fold lines 17 and 18, respectively. The top flap 14 is integrally ~onnected to the top edge of the front panel 11 along tear llne 19.
Tear line 19 comprises, for example, a line of perforations.
A second tear line 20 is provided on the top flap 14 to define, in conjunction with tear line 19, a tear strip 21.
The front panel 11 and the back panel 15 are integrally connected along a common bottom edge 22. The resealing flap 16 is integrally connected to the back panel 15 along fold line 23, and is provided with a second fold line 24. Envelope blank 10 contains adhesive strips 25, 26, 27 and 28 which are applied to the side flap 12, the side flap 13, the top flap 1 and the resealina flap 16, respec-tively. The front panel 11 may be provided with one or more viewing windows 29 spaced above the bottom edge 22 of the front panel 11. As illustrated in Figure 6, the outer fa~e of resealing flap 16 bears indicia of the return address.
- The formed envelope gener~lly desigr!ateà by ~he number 30 in Figures 3 and 4, is assembled from the blank 10 ~. =
~ 'îJ'796 previously described when reference was made to Figure 1.
As shown,for example, in Figure 4, the envelope blank may contain printed or written indicia as desired for usage instructions, addresses, permit postage information, or the like. .
The original addressee may have usage instructions sequentially presented where the instructions are provided, in part, on the tear strip 21 for viewing prior to removal of the tear strip 21 and, in part, on the upper portion of the back panel 15 for viewing after removal o~ the tear strip 21.
Formation of the envelope 30 from envelope blank 10 takes place as follows. The resealiny flap 16, shown in Figure 1, is folded along fold line 23 so that the resealing flap 16 overlies a portion of the inner face of back panel 15. The back panel 15 is then folded along the bottom edge 22 to overlie a portion of the inner face of front pane' 11.
The portion of the inner face of front panel 11 which is not covered by back panel 15 is a thin strip, on the order of one-eighth inch in width, along the top edge of the front panel 11. The thin strip is shown in Figure 2 2s that portion of the inner face of the front panel 11 exposed between the tear line 19 and the fold line 23. The side flaps 12 and 13 are then folded along fold lines 17 and 18, respectively, and secured by adhesive strips 25 and 26, respectively, to the outer face of the back panel 15, there-by providing 2n envelope pocket with an open end portion between fold line 23 and the tear line 19 as shown in Figure 2.

, -- For first mailing, an enclosure 31, sectionally , illustrated in Figure 5, may be inserted within the envelope i pocket open end and sealed therein by folding the top flap 14 along tear line 19 to overlie a portion of the side flaps 12 and 13 and the back panel 15 as shown in Figure 3. The top flap 14 is secured by adhesive strip 27 to portions of the outer faces of the side flaps 12 and 13 and the back panel l5. The address of the original addressee, borne by the enclosure 31 is visible through the viewing window 29 ln the front panel 11 as shown in Figure ~. As noted, the window 29 is optional; if none is provided, the address of the original addressee can be written, typed, or placed on the envelope front by an address strip.
Upon receipt, the original addressee opens the envelope by tearing along tear lines 19 and 20, thus remov-ing the tear strip 21 and exposins the conlents of the envelope. The original addressee may also open the enve-lope along its top edge by using automatic or manual envelope opening devices without danger of inadvertently severing the resealing flap 16 from the back panel 15.
The original addressee then removes the conter.ts of the envelope, including enclosure 31 (unless enclosure 31 is needed for re~urn to the sender or for display of a return address or other information through window 29), and pulls the resealing flap 16 from within the envelope pocket.
F_r second mailing, an appropriate response, such as enclo-sure 32, sectionally illustrated in Figure 7, is inserte~
~ '7'796 ;; , . . .
within the envelope pocket and sealed therein by folding the resealing flap 16 along fold line 24 to overlie a portion of the outer face of the front panel 11 as shown in Figure 6.
The resealing flap is secured by adhesive 28 to a portion of the front panel 11. with proper postage placed on the outer face of the resealing flap 16, the envelope is ready for return mailing to the original sender at the return address b~rne by the resealing flap 16. The return address may be placed on the resealing flap by preprinting, by affixing an address label thereon, by writing, or by other suitable methods.
In another preferred embodiment, the front panel is plain, without one or more viewing windows. The address of the original addressee may in this embodiment be placed on the front panel 11, as modified, by preprinting, by fixing an original address label thereon, by writing, or by other suitable methods.
In yet another preferred embodlment, the remail-able envelope utilizes a resealing flap of sufficiently shortened length so that one or more viewing windows pro-vided in the front panel are exposed when the envelope is in its remailing configuration. This embodiment is illustrated in Figure 8, in which the resealing flap 50 is G shortened version of the resealing flap 16. The viewing window 51 corresponds to the window ~9 of Figure 1, and the front panel 52 corresponds to the front panel 11.
c 9~
l l . ' .
' In still another embodiment, the remailable enve-lope utilizes a tear strip in the front panel instead of in ', the top flap. This embodiment is illustrated in Figures 9 l and 10 which are similar to Figures 1 and 4, respectively, wherein like numbered elements are the same and wherein the tear strip 128 is defined by tear lines 19, 125, 126 and 127. In this embodiment, usage instructions may be provided, in part, the tear strip 128 for viewing prior to the tear strip 128's removal and, in part, on the upper portion of the resealing flap 16 for viewing after removGl of the tear strip 128.
, Obviously, many modifications and variations of the present invention are possible in light of the above teachings. For example, it is contemplated t~at the panel and flaps of the remailable envelope may be of different design and arrangement, that the envelope may or may not contain written or printed indicia, and that the envelope may be provided with additional viewing windows. It is, therefore, to be understood that within the scope of the appended claims,'the invention may be practiced otherwise thar. as speciflc211y described.

To obviate the need for a separate forwarding envelope and a separate return envelope for each original addressee, it is known to provide remailable or "two-way"
envelopes which serve both the forwarding and the return functions. One such known two-way envelope utilizes a resealing flap carried by the back panel of the forwarding envelope, to reseal the envelope for return mailing.

Furthermore, the desired rem~ilability of prior art envelopes can be destroyed by the use of automatic or manual envelope openers which may sever the resealing flap from the body of the envelope. There are also two-way envelopes known to the prior arl which are designed in such a manner that enclosures cannot be sent in one or both directions of envelope travel.
Examples of prior art envelopes are described in U.S. Patents Nos. 1,953,192; 2,931,559i 3,874,582; 3,9&2,689;

U.S. Patent No. 3,874,582 provides a two-way envelope comprising a front panel with a window, a bottom flap, two opposed side flaps with detachable upper portions and a detachable top flap. Upon receiving the envelope, the original addressee removes the three detachable portions from the envelope to form a smaller sized return envelope wlth a newly formed.top resealing flap. For return mailing, the origlnal addressee inserts a response into the envelope pocket, inserts an enclosure containing the return address so that the return address can be seen through the window, and then folds and seals the newly formed top resealing flap to the back panel. Again, the comple~ity of transforming the original envelope into a usable return envelope detxacts from the usefulness and acceptability of the two-~ay envelope design.
U.S. Patent No. 3,982,689 illustrates another two-way mailing envelope, including a window and an enclosure to be transmitted therein. The envelope is usable for return mailing by tearing a top flap from the front panel of t~.e envelope and thereby exposing a resealing flap which, being the upper portion of the back panel, is then folded c 1~'7'7'i~96 toward and attached to the front panel. Thus, the remailing envelope is smaller than the original envelope by the length of the top flap which is r!emoved by the original addressee for en~elope opening. Thus the envelope also reguires an enclosure with two address areas for exposure through the window. Additionally, opening the envelope without removing the tearable top flap will not properl~7 expose the resealing flap for folding and securing to the front panel for remaillng.
The foregoing complexities of operation, including modification of the enclosure bearing the return address, detract from the usefulness and acceptability of this envelope design.
- U.S. Patent No. ~,089,418 describes a returnable envelope consisting of a blank having a main panel and flaps foldable from each edge. For original mailing, the envelope is formed by inwardly folding twc opposed side flaps, by upwardly folding a bottom flap, and by downwardly folding a top panel.

From the foregoing considerations, it should be apparent that there is a great need for a remailable envelope which may be manufactured, stuffed and mailed by high speed automatic machines, which can be opened by automatic or manual envelope opening devices without destroying remailability, and which is simple in use for original mailing and remailing. The subject invention is directed to just such an envelope.
SUMMARY OF THE INVENTION
The subject invention provides an envelope formed from an envelope blank which is symmetrical about its center line, said envelope comprising a front panel having a top edge, a bottom edge and two side edges; a pair of opposed side flaps, each of which is integrally connected to said front panel at first fold lines along one of said front panel side edges; a back panel integrally connected to said front panel bottom edge at a second fold line and having a top edge and two side edges;
a resealing flap integrally connected to said back panel top edge at a third fold line; a top flap integrally connected to said front panel top edge at a fourth fold line; first adhesive means for securing said side flaps in overlying relation to said back panel folded along said front panel bottom edge to overlie a portion of the inner face of said front panel; second adhesive means for securing said top flap in overlying relation to the outer face of said back panel to seal the envelope for first mailing; and third adhesive means for securing said reseal-ing flap in overlying relation to the outer face of said front panel to seal the envelope for second mailing. Being symmetxical about its center line, the envelope blank readily may be cut, printed, folded, and formed into an envelope in "web-type" automatic envelope making machines.
From another aspect, the invention provides a method of making the envelope as aforesaid, the method comprising the ti steps of: folding said resealing flap along said third fold line to overlie a portion of the inner face of said back panel;
folding said back panel along said second fold line to overlie the inner face of said front panel; and folding and securing by said first adhesive means said side flaps in overlying relation to said back panel.
In preparation for original mailing, the envelope blank is folded so that the common edge between the resealing flap and the back panel is at an appropriate spacing below the top edge of the front panel when the back panel is folded to overlie the front panel. The allowance of this spacing enables any enclosures to automatically be inserted into the envelope by automatic insertion machines.
Prior to original mailing, the top flap is adhesively sealed to the back panel of the envelope providing security and privacy in mailing. In one embodiment, the envelope is received by the original addressee and is opened by removing the tear strip from the top flap or by opening the envelope along its top edge by conventional automatic or by manual opening devices.
The spacing referred to above also protects the resealing flap from inadvertently being severed from the back panel if the envelope opened with automatic or manual opening devices. In another embodiment, the envelope is opened by removing a tear strip located on the front panel or by opening the envelope along its top edge by manual or automatic opening devices as noted above. The original addressee removes any contents of the envelope, pulls the resealing flap from the envelope folds, and inserts what is to be remailed within the envelope pocket.
In one embodiment, the original addressee folds and secures the xesealing flap over the front panel or window thereby exposing for mailing the return address borne by the outer side of the resealing flap. In another embodiment, the original addressee '7~
folds and secures to the front panel a shorter resealing flap which does not cover the entire viewing window. In all embodi-ments, placing the envelope in its remailing configuration does not require complex manipulation, and does not reduce the length or the width of the envelope as originally mailed.
Advantages of this invention will further become apparent hereinafter and with reference to the accompanying drawings.

I DESCRIPTION OF THE PREFERRED EMBODIMENTS
"
The subject invention will now be described with reference to the drawings, in which Figure 1 illustrates an envelope blank made frGm paper or other suitable matexial and generally designated by the numeral 10. Envelope blank 10 includes a front panel 11, a pair of opposed foldable side flaps 12 and 13, a top flap 14, a back panel 15, and a resealing flap 16. The side flaps 12 and 13 are integrally connected to the front panel 11 along fold lines 17 and 18, respectively. The top flap 14 is integrally ~onnected to the top edge of the front panel 11 along tear llne 19.
Tear line 19 comprises, for example, a line of perforations.
A second tear line 20 is provided on the top flap 14 to define, in conjunction with tear line 19, a tear strip 21.
The front panel 11 and the back panel 15 are integrally connected along a common bottom edge 22. The resealing flap 16 is integrally connected to the back panel 15 along fold line 23, and is provided with a second fold line 24. Envelope blank 10 contains adhesive strips 25, 26, 27 and 28 which are applied to the side flap 12, the side flap 13, the top flap 1 and the resealina flap 16, respec-tively. The front panel 11 may be provided with one or more viewing windows 29 spaced above the bottom edge 22 of the front panel 11. As illustrated in Figure 6, the outer fa~e of resealing flap 16 bears indicia of the return address.
- The formed envelope gener~lly desigr!ateà by ~he number 30 in Figures 3 and 4, is assembled from the blank 10 ~. =
~ 'îJ'796 previously described when reference was made to Figure 1.
As shown,for example, in Figure 4, the envelope blank may contain printed or written indicia as desired for usage instructions, addresses, permit postage information, or the like. .
The original addressee may have usage instructions sequentially presented where the instructions are provided, in part, on the tear strip 21 for viewing prior to removal of the tear strip 21 and, in part, on the upper portion of the back panel 15 for viewing after removal o~ the tear strip 21.
Formation of the envelope 30 from envelope blank 10 takes place as follows. The resealiny flap 16, shown in Figure 1, is folded along fold line 23 so that the resealing flap 16 overlies a portion of the inner face of back panel 15. The back panel 15 is then folded along the bottom edge 22 to overlie a portion of the inner face of front pane' 11.
The portion of the inner face of front panel 11 which is not covered by back panel 15 is a thin strip, on the order of one-eighth inch in width, along the top edge of the front panel 11. The thin strip is shown in Figure 2 2s that portion of the inner face of the front panel 11 exposed between the tear line 19 and the fold line 23. The side flaps 12 and 13 are then folded along fold lines 17 and 18, respectively, and secured by adhesive strips 25 and 26, respectively, to the outer face of the back panel 15, there-by providing 2n envelope pocket with an open end portion between fold line 23 and the tear line 19 as shown in Figure 2.

, -- For first mailing, an enclosure 31, sectionally , illustrated in Figure 5, may be inserted within the envelope i pocket open end and sealed therein by folding the top flap 14 along tear line 19 to overlie a portion of the side flaps 12 and 13 and the back panel 15 as shown in Figure 3. The top flap 14 is secured by adhesive strip 27 to portions of the outer faces of the side flaps 12 and 13 and the back panel l5. The address of the original addressee, borne by the enclosure 31 is visible through the viewing window 29 ln the front panel 11 as shown in Figure ~. As noted, the window 29 is optional; if none is provided, the address of the original addressee can be written, typed, or placed on the envelope front by an address strip.
Upon receipt, the original addressee opens the envelope by tearing along tear lines 19 and 20, thus remov-ing the tear strip 21 and exposins the conlents of the envelope. The original addressee may also open the enve-lope along its top edge by using automatic or manual envelope opening devices without danger of inadvertently severing the resealing flap 16 from the back panel 15.
The original addressee then removes the conter.ts of the envelope, including enclosure 31 (unless enclosure 31 is needed for re~urn to the sender or for display of a return address or other information through window 29), and pulls the resealing flap 16 from within the envelope pocket.
F_r second mailing, an appropriate response, such as enclo-sure 32, sectionally illustrated in Figure 7, is inserte~

within the envelope pocket and sealed therein by folding the resealing flap 16 along fold line 24 to overlie a portion of the outer face of the front panel 11 as shown in Figure 6.
The resealing flap is secured by adhesive 28 to a portion of the front panel 11. with proper postage placed on the outer face of the resealing flap 16, the envelope is ready for return mailing to the original sender at the return address b~rne by the resealing flap 16. The return address may be placed on the resealing flap by preprinting, by affixing an address label thereon, by writing, or by other suitable methods.
In another preferred embodiment, the front panel is plain, without one or more viewing windows. The address of the original addressee may in this embodiment be placed on the front panel 11, as modified, by preprinting, by fixing an original address label thereon, by writing, or by other suitable methods.
In yet another preferred embodlment, the remail-able envelope utilizes a resealing flap of sufficiently shortened length so that one or more viewing windows pro-vided in the front panel are exposed when the envelope is in its remailing configuration. This embodiment is illustrated in Figure 8, in which the resealing flap 50 is G shortened version of the resealing flap 16. The viewing window 51 corresponds to the window ~9 of Figure 1, and the front panel 52 corresponds to the front panel 11.

' In still another embodiment, the remailable enve-lope utilizes a tear strip in the front panel instead of in ', the top flap. This embodiment is illustrated in Figures 9 l and 10 which are similar to Figures 1 and 4, respectively, wherein like numbered elements are the same and wherein the tear strip 128 is defined by tear lines 19, 125, 126 and 127. In this embodiment, usage instructions may be provided, in part, the tear strip 128 for viewing prior to the tear strip 128's removal and, in part, on the upper portion of the resealing flap 16 for viewing after removGl of the tear strip 128.
, Obviously, many modifications and variations of the present invention are possible in light of the above teachings. For example, it is contemplated t~at the panel and flaps of the remailable envelope may be of different design and arrangement, that the envelope may or may not contain written or printed indicia, and that the envelope may be provided with additional viewing windows. It is, therefore, to be understood that within the scope of the appended claims,'the invention may be practiced otherwise thar. as speciflc211y described.
